长公路隧道交通安全研究

由于在长公路隧道中行驶时车道相对封闭、光线时强时弱、行车自由度偏小、空气不易流通等，在隧道内易发生交通事故，而且交通事故发生后易引起火灾，产生的浓烟较难疏散，事故后果及事故救援方法都与其他的交通事故不同。随着隧道交通事故数量不断增加，隧道已经成为交通事故的主要空间分布点和事故黑点。采用事故致因理论，详细分析了造成交通事故的各种原因，找出了引发事故的根源，然后提出了一系列隧道交通安全措施。最后构建了公路隧道交通事故应急系统，可最大程度减少交通事故损失。

Study on Long-Highway-Tunnel Traffic Safety

Because in long highway tunnel, the lane is relatively close, the light is sometimes strong and sometimes weak, the freedom-degree of driving is on the small side and the air is difficult to circulate, the traffic accident occur frequently in the tunnel. Traffic accidents in tunnel easily cause a fire with dense smoke and cause difficulty for evacuation. The accident consequence and the rescue method are different from other traffic accidents. As the quantity of traffic accident of the tunnel is increasing constantly, the tunnel has already become main space distribution and accident black point of the traffic accident. By use of accident causation theory, detailed analysis is made on causes of the traffic accident, the causation of the accident is given and a series of tunnel traffic safety measures are proposed. Finally, the tunnel traffic accident emergency system is constructed, which can reduce traffic accident loss to the minimum.
